Map of the chemical-physical properties - pH values in the soils of the Emilia-Romagna plain between 0-30 cm. Outdated

Soil pH is a fundamental property that can influence many physical, chemical and biological processes. It regulates the availability of many nutrients for plants, influences the activity of microorganisms responsible for the decomposition of organic matter and most of the chemical transformations that take place in the soil, has a decisive role in influencing mobility and therefore the bioavailability of heavy metals. In addition, some physical characteristics of the soil such as permeability, stability of the aggregates, the degree of compaction and the dispersion of the clay fraction are influenced by pH. The map represents the area distribution in the lowland soils of the pH value in the surface layer (0-30 cm). The map was drawn up on the basis of data extracted from the database of soils of the Emilia-Romagna Region for the period 1974-2017.
